JOHN STIVERS – WORK ENERGY POWERThis video breaks down WORK, ENERGY and POWER into an easily understood explanation.

Well let’s start with work. Physicists define work as a force applied over a distance. If you take an object, say a toolbox and apply a force, 22 pounds of force and you move it two feet, you’ve done 44 foot pounds of work. In metric those units convert to 100 newtons of force, and let’s say we moved it 0.60 of a meter. So we’ve done 60 newton-meters of work. In the metric system that’s referred to as a joule, 1 newton-meter is 1 joule. Continue reading the transcript. energy-101.org

HOW TO CONVERT DATA IN ONE UNIT OF MEASURE TO A DIFFERENT UNIT OF MEASURE?www.eia.gov

1 Joule (J) is the MKS unit of energy, equal to the force of one Newton acting through one meter.
1 Watt is the power of a Joule of energy per second

Power = Current x Voltage (P = I V)
1 Watt is the power from a current of 1 Ampere flowing through 1 Volt.
1 kilowatt is a thousand Watts.
1 kilowatt-hour is the energy of one kilowatt power flowing for one hour. (E = P t).
1 kilowatt-hour (kWh) = 3.6 x 106 J = 3.6 million Joules

According to Google, the energy it takes to conduct 100 searches on its site is equivalent to a 60-watt light bulb burning for 28 minutes. Google uses about 0.0003 kWh of energy to answer the avenge search query, which translates into about 0.2 g of carbon dioxide released.

In the average home, 75% of the electricity used to power home electronics is consumed while the products are turned off. The average desktop computer idles at 80 watts, while the average laptop idles at 20 watts. A Sony PlayStation 3 uses about 200 watts and nearly as much when idle. Idle power consumes more electricity than all the solar panels in America combined.

Only 10% of energy in a light bulb is used to create light. Ninety percent of a light bulb’s energy creates heat. Compact fluorescent light bulbs (CFLs), on the other hand, use about 80% less electricity than conventional bulbs and last up to 12 times as long.

The amount of energy Americans use doubles every 20 years.

The United States produces more nuclear-generated electricity than any other country, nearly 1/3 of the world’s total. The second largest producer is France, which generates more than 3/4 of its electricity in nuclear reactors.

The top seven oil consumers combined use more than half of the world’s total. The United States alone uses more than a quarter.

More than 1/5 of the world’s primary energy is used for transport, followed by industry, construction, and agricultures. Much is in the form of gasoline, of which nearly 792.5 million gallons is burned every day.

A hurricane releases 50 trillion to 200 trillion watts of heat energy. This is as much energy as a 10-megaton nuclear bomb exploding every 20 minutes.

The United States represents less than 5% of the world’s population, yet Americans account for 25% of the world’s commercial energy consumption and 22% of the world’s industrial emissions of CO2.

Cars amount to three-quarters of all transportation emissions. At the current rate, there will be over a billion cars in 2030, and a billion more by 2050.

Since the beginning of the Industrial Revolution, the ocean’s acidity has increased by approximately 30%.

Scientists expect a 3.5° F increase in average global temperatures by the year 2100, resulting in the warmest temperatures in the past million years. The last time the Earth was this warm 1.8 million years ago, when sea levels were also 12-18 feet higher.

Swedish scientist Svante Arrhenius was the first to note in 1896 that fossil fuel combustion could result in global warming.

Cows burping, pooping, and emitting gas release over 13 million tons of methane each year, which is 70% more emissions than the oil and gas industry. After carbon dioxide, methane is the most widespread greenhouse gas.

In 1910, Glacier National Park in Montana boasted 150 glaciers—today there are just 27.

Without the atmosphere to create a greenhouse-type effect, the average temperature on Earth would be just 5° Fahrenheit (F).

Fossil fuel burning currently adds nearly six billion tons of CO2 to the atmosphere every year. Only half of this CO2 is removed by forests and oceans.

Lewis and Clark spent more time in North Dakota than in any other place they visited on their expedition.

The world’s largest hamburger was eaten in Rutland, North Dakota. It weighed 3,591 pounds and more than 8,000 people were invited to the meal.

North Dakota farmland would cover over 12 million city blocks. Farmers there produce enough wheat each year to make 12.6 billion loaves of bread.

It’s illegal to go dancing in Fargo with a hat on. It is even illegal to wear a hat at a party where other people are dancing. It is also illegal in North Dakota to take a nap with your shoes on. After 11 pm, it is illegal to set off fireworks at Devil’s Lake in North Dakota.

Today, 104 nuclear plants supply about 20% of the United State’s electricity. The oldest plants have been operating since before 1979. There have been no new sites built since the Three Mile Island disaster (1979).

In the United States, radioactivity is often measured in rems. However, most countries currently use the sievert (Sv) to measure radioactivity. One sievert is equal to 100 rems. The nuclear waste from an entire reactor gives off about 10,000 rems per hour, even 10 years after it was first used in a nuclear plant. A human who is exposed to 500 rems at one time will die.

Waste from the 1979 Three Mile Island accident is stored in Idaho, even though Idaho has never had a commercial reactor. Illinois has the most spent nuclear fuel of any other state in the U.S. at 9,301 tons. It is followed by Pennsylvania (6,446 tons), South Carolina (4,290), and New York and North Carolina (3,780 tons each).

The Sun produces an enormous amount of energy from its nuclear reactions that change hydrogen into helium. In the process, the Sun loses over 4 million tons of mass—every second.

Just removing a person’s outer clothing can remove 90% of the radioactive material after a disaster.
